INTERNAL DEFOLIANT DISPENSER A/A45Y-1.
Abstract
The internal defoliant dispenser provides for loading, transporting, and dispensing of 958 gallons of defoliant chemical, and in case of an emergency, dumping the full load of chemical overboard in less than one minute. The dispenser was designed to deliver agent at a concentration of three gallons per acre over an effective swath width of 120 feet from an altitude of 150 feet in either the C-123 or C-130 aircraft. The results of tests conducted at Eglin Air Force Base, Florida indicated that the optimum parameters for the C-130 aircraft were an altitude of one hundred feet and a maximum swath of seventy feet to obtain a concentration of three gallons per acre. The optimum parameters for the C-123 aircraft were an altitude of 150 feet and a maximum swath of 40 feet for the same concentration. The fuselage-mounted spray boom does not deliver the defoliant agent far enough outboard to be affected by the action of the wingtip vortices. Previous testing with defoliant agent demonstrated that wing mounted booms subject the spray to these vortices and produce wider swath width. It is recommended that an optimized wing boom be developed in order to increase the swath width. (Author)
